Using External Amplifiers
Use connectors on top of controller to access necessary signals to run external amplifiers. In order to use the full
torque limit, make sure the AG setting for the axes using external amplifiers are set to 0 or 1. Set the BR command
to 1 for any axis that will be setup to run external amplifiers (this will disable the hall error protection). For more
information on connecting external amplifiers, see Step 2b. Connecting External Amplifiers and Motors in Chapter
2.
ELO Input
If the ELO input on the controller is triggered, the amplifier will be shut down at a hardware level, the motors will
be essentially in a Motor Off (MO) state. TA3 will return a 3 and the #AMPERR routine will run when the ELO input
is triggered. To recover from an ELO, an MO followed by a WT 2, and an SH must be issued, or the controller must
be reset.
It is recommended that OE1 be used for all axes when the ELO is used in an application.
See the Optoisolated Input Electrical Informationsection in Chapter 3 Connecting Hardware for information on
connecting the ELO input.
